Rack Precautions
The following are important precautions concerning rack setup:
• The enclosure unit is heavy and requires at least two people to lift it.
• Ensure that the leveling jacks on the bottom of the rack are fully extended to the
floor with the full weight of the rack resting on them.
• In single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations the racks frames should be grounded to the same earth
ground as the electrical source for the power supplies by means of a grounding
strap.
Server Precautions
The following are important precautions concerning server setup:
• Review the electrical and general safety precautions in Chapter 2 .
• Determine the placement of each component in the rack before you install the rails.
• Install the heaviest server components on the bottom of the rack first, and then work
up.
• Use a regulating uninterrupted power supply (UPS) to protect the server from power
surges, voltage spikes and to keep your system operating in case of a power failure.
• Allow the hot plug hard drives and power supply units to cool before touching them.
• Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
Rack Mounting Considerations
Below are listed important considerations for rack mounting.
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating temperature of
the rack environment may be greater than the ambient temperature of the room.
Therefore, consideration should be given to installing the equipment in an environment
compatible with the manufacturer’s maximum rated ambient temperature. Refer to
Appendix E for operating temperature specifications.
Reduced Airflow
Equipment should be mounted into a rack so that the amount of airflow required for safe
operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise
due to uneven mechanical loading.
